Potential Causes of Computer-Related Eye Symptoms
It has been widely proven by many researches that PC monitors will not cause any permanent ocular or visual damage.
However, computer-related eye complaints have been continuing to increase during the past decades.
Then, what is the real reason for this phenomenon? People living in the world especially in those thriving countries such as China and India are increasingly in need for computer in the workplace.
In other words, the dependence on computer is on the rise.
A concerning problem is that long hours of computer work will very likely cause certain eye conditions, such as irritation, difficulty in focusing and blurriness.
Non-ocular symptoms include neck aches and backaches.
Many computer users may have similar complaints.
Since these conditions are not caused by PC monitors themselves, there are surely other causes.
A special group of people is more frequently associated with computer-related visual symptoms.
They are individuals who have refractive errors.
During computer work, it is necessary for these people to put on their eyeglasses normally.
Uncorrected or undercorrected eyes are easier to suffer eye fatigue.
For people with presbyopia, reading glasses or bifocal glasses should be used.
Another possible cause of the above complaints is improper settings of the computer.
There are a lot of associated sources of eyestrain, like intensity, focus, clarity of letters, the brightness and contrast of the monitor and so on.
It is also possible to alleviate eyestrain by covering an ultraviolet and infrared screen over the monitor.
Eyestrain during computer use can also be caused by other factors in the environment.
The work station needs the user's particular attention.
The computer monitor should be viewed in proper lighting and position.
Even the exact seat height and the detailed viewing angle should be considered.
Furthermore, some computer users may forget to blink while staring at the monitor.
This is highly discouraged.
A right way is to get periodic rest breaks, which will ease eye fatigue effectively.
